Monday I discovered why Zman safety wires the swingarm adjusters to the
swing arm. Always wondered.
Mine are ten years old with many many adjustments. The adjuster bolts
are nice and sloppy.
The left bolt backed out ( in two sessions) far enough to allow the
adjuster pop out of the swingarm. ( Note, the axle was tight and held
the wheel perfectly, the adjuster just backed out.)
When the swingarm adjuster backs out far enough it can turn sideways.
When it turns sideways one end hits free air, the other end hits the
sprocket. My Vortex sprocket now has a nice wide groove worn into it,
and I am LUCKY the adjuster did not turn a bit more and go into the
sprocket holes, thus destroying the adjuster, sprocket, swingarm, and
probably my bike as the rear sprocket locked up.
